DETAILED DESCRIPTION

A display module for displaying content may be attached to a computingdevice body via an adhesive, such as a pressure-sensitive adhesive. Tosupport the display module, the body may include an inwardly extendingdeck to which the display module is adhered. FIG. 1 shows an exampleelectronic display device 100 including a display module 102 and a body104 holding the display module 102.

FIG. 2 shows a partial cross-section of the example electronic displaydevice 100, illustrating the display module 102 positioned within thebody 104. Other internal components are omitted for clarity. The body104 comprises a protective wall 200, and a deck 202 extending inwardlyfrom the wall 200. The display module 102 is adhered to the deck 202such that the wall at least partially surrounds the display module 102.The display module 102 may comprise a plurality of layers, such as twoelectrode layers separated by a dielectric layer in some examples, butis depicted herein as a single layer. The display module 102 may alsoinclude a touch detection component, such as one or more sensor layers,in examples where the display device 100 is also a touch-sensitivedisplay device.

As mentioned above, the display module 102 may be adhered to the deckusing a pressure-sensitive adhesive (PSA) 204. Placement of the PSA 204onto the deck for attachment of the display module 102 may posechallenges. For example, a PSA placement fixture in an assembly processmay not directly reference the PSA 204 to the body 104 and/or the deck202. Instead, the PSA placement fixture may reference a differentportion of the fixture that holds the body. As a result, the tolerancestackup, which represents accumulated variations allowed by specifiedpart and placement tolerances, may include tolerances for the placementof the PSA on the fixture, for the placement of the body on the fixture,for the dimensions of the PSA and body component parts, and for thealignment of the PSA fixture component to the body fixture component, asexamples. In some instances, the tolerance stackup for the placement ofthe display module on the body of device 100 may result in a PSAplacement accuracy of +/−0.3 mm.

Misalignment of the PSA may affect adhesion performance and/or havevisible effects on the device 100. For example, continuing with FIG. 2,a small gap 206 is located between an outer edge of the display module102 and the wall 200. If the PSA 204 is placed too close to the wall200, the PSA 204 may extend beyond the outer edge of the display module102 such that it is visible through the gap 206. Dust may adhere to thePSA 204 in the gap 206 as well, which also may be visible. Thus, toavoid such effects, the PSA 204 may be configured not to extend into thegap 206 even at a maximum of the tolerance range. FIG. 2 shows, forexample, a designed-in tolerance gap 208 between the PSA 102 and thewall 200 of the body 104 to account for the placement accuracy range ofthe PSA 204. However, the use of the tolerance gap 208 may result in anouter edge of the display module 102 extending beyond an outer edge ofthe PSA 204 by an average of approximately 0.3 mm, and by as much as 0.6mm at the other end of the tolerance range.

Accordingly, examples are disclosed that may help to reduce a magnitudeof the tolerance stackup in a PSA application process. Briefly, thedisclosed methods utilize a PSA application fixture that directlyreferences a deck of a body of a display device when placing the PSA onthe deck. Directly referencing fixture to the deck may help to tightenthe tolerance stackup compared to methods in which such directreferencing is not used. In some examples, the disclosed examples mayallow a tolerance of 0.10-0.25 mm to be achieved.

FIG. 3 shows an example PSA application fixture 300 in the form of aclamshell structure having a PSA-applicator portion 301 to hold PSAassemblies 302 a and 302 b, and a body-supporting portion 303 to hold adevice body 304. The PSA-applicator portion 301 includes PSA holdingfeatures 305 a and 305 b. Other examples may have either more or fewerPSA holding features. Each PSA holding feature 305 is configured to holda strip-shaped PSA assembly to the fixture 300 by vacuum or in any othersuitable manner for application to a corresponding side of the body 304.For example, the PSA holding feature 305 a is shown holding PSA assembly302 a, and the PSA holding feature 305 b is shown holding PSA assembly302 b. The PSA assembly 302 a includes a PSA 306 on one side and areleasable support 307 on the other side, with the side having thereleasable support 307 held to the PSA application fixture 300. The PSAassembly 302 b is similarly configured. In other examples, a PSA holdingfeature may be configured to hold a PSA assembly of any other suitableshape than a strip shape.

Each PSA holding feature includes a vacuum head comprising a pluralityof holes to draw a vacuum for holding a PSA assembly to the PSA holdingfeature. This is described in more detail below with regard to FIG. 4A.Each PSA holding feature further includes index features for interfacingwith corresponding reference features on the body 304, as shown at 308and 309 for the PSA holding feature 305 a. Various mechanical featuresnot depicted in FIG. 3 (e.g. motors, controllers, etc.) may be includedto control the movement of parts of the PSA application fixture 300during a PSA application process.

The fixture 300 is shown in FIG. 3 in an open configuration. In thisconfiguration, the PSA assemblies 302 a and 302 b may be placed on thePSA holding features 305 a and 305 ba, and a vacuum applied to hold thePSA assemblies in place. Further, the body 304 may be placed on thebody-supporting portion 303 of the PSA application fixture 300. The PSAapplication fixture 300 then may be rotated on a hinge to move the PSAassemblies 302 a and 302 b closer toward a deck 312 of the body 304 suchthat the PSA assembly 302 a moves toward a first side 312 a of the body304 and the PSA assembly 302 b moves toward a second side 312 b of thebody 304, as indicated schematically by the dotted arrows. Movements ofparts of the PSA application fixture 300, application/release of vacuum,and/or other functions of the PSA application fixture may be controlledby a computing system 314, described in more detail with regard to FIG.10.

FIG. 4A shows a magnified view of the PSA holding feature 305 a, andFIG. 4B shows the PSA holding feature 305 a with the PSA assembly 302 aheld thereto. The PSA holding feature 305 a includes a frame 400 and avacuum head 402 having a plurality of holes 404 through which a vacuummay be applied to the releasable support 307 of the PSA assembly 302 a.In other examples, the PSA assembly 306 may be held in place by amechanism other than via a vacuum, such as a mechanical clasp.

As mentioned above, the PSA holding feature 305 a includes a first indexfeature 308 and a second index feature 309 configured to directlyreference respective features in the deck 312 of the body 304 to helpalign the PSA assembly 302 a to the body 304. The PSA assembly 302 a maybe cut from a longer PSA strip using a cutting die manufactured with adesired degree of accuracy. The die cutting of the PSA assembly 302 amay form holes in the PSA assembly 302 a corresponding to the locationsof the first index feature 308 and the second index feature 309. Thismay allow a positional tolerance of the PSA assembly 302 a on the PSAholding feature 305 a to be maintained at a desired level. Then, the PSAassembly 302 a may be placed onto the deck 312 of a device body bydirectly referencing the first index feature 308 and the second indexfeature 309 to the device body 304. Thus, the tolerance stackup for theplacement of the PSA using such direct referencing of the fixture to thedevice body may include tolerances for the dimensions of the PSA and forthe reference features formed within the body, which is a lesser numberof components than the tolerance stackup for the fixture-to-fixturereferencing described above. This may help to achieve a relativelytighter tolerance for PSA placement, and thus may allow the use of asmaller built-in tolerance gap for the PSA. The first and second indexfeatures 308, 309 are shown in FIGS. 3, 4A and 4B as alignment pins,though they may take any other suitable form(s).

FIG. 5 shows a partial perspective view of the PSA holding feature 305 ahaving been rotated to a first position relative to the device body byclosure of the clamshell structure of the PSA application fixture 300.Other portions of the PSA application fixture 300 are omitted from thisfigure for clarity. In this configuration, the first index feature 308and the second index feature 309 have not yet contacted the body 304,and the PSA 306 has not yet been applied to the deck. As shown, thefirst index feature 308 on the PSA application fixture 300 is configuredto interface with a first, “rotational” reference feature 500 of thebody 304, where the first reference feature 500 is an elongatedindentation formed in an inner edge of the deck 312. Likewise, thesecond index feature 309 is configured to interface with a second,“translation-fixing” reference feature 502 of the body 304, where thesecond reference feature 502 is a semicircular indentation also formedin the inner edge of the deck 312 with a shape that accurately matchesthe shape of the second index feature 309. The first reference feature500 may allow an initial reference point to be established andmaintained with the inner edge of the deck 312 via the first indexfeature 308. Once this initial reference point is established, thesecond index feature 309 is then moved into the second reference feature502 via rotation about the first index feature 308 and possiblytranslation of the first index feature 308 within the first referencefeature 500. Placement of the second index feature 309 within the secondreference feature 502 limits both further rotation and translation. Assuch, once both the first and second index features 308, 309 arerespectively placed into the first and second reference features 500 and502, the PSA 306 is positioned relative to the deck 312 at a desiredaccuracy. While shown here as ellipsoidal indentations, it will beunderstood that each of reference features 500 and 502 may take anyother suitable form, such as an indentation comprising one or moreangles, e.g. a triangular-shaped or rectangular-shaped cutout, asnon-limiting examples. Further, in some examples, the reference features500 and 502 may have the same configuration.

FIG. 6 shows a partial cross-sectional view taken along line 6-6 of FIG.5, illustrating a side view of the PSA application fixture 300 with theclamshell rotated closed but the PSA assembly 302 a not yet aligned tothe deck. This position may be referred to as a closed, unalignedposition. In the depicted figure, the second index feature 309 has notyet been brought into contact with the second reference feature 502.Next, FIG. 7 shows a partial, side cross section of the PSA applicationfixture 300 in a closed, aligned position while contacting the body 304.Here, the second index feature 309 is shown as being positioned withinand contacting the second reference feature 502. In this position, thePSA assembly 302 a is properly aligned relative to the body 304, but notyet adhered to the body 304. The various components of the PSAapplication fixture 300 may be configured to move to the alignedconfiguration including but not limited via a servomechanism or springbias.

FIG. 8 shows a partial, side cross section of the PSA applicationfixture 300 in an aligned and engaged position, in which the PSAassembly 302 a is adhered to the body 304. To bring these componentsinto contact, the PSA application fixture 300 may lift the body 304toward the PSA assembly 306 to make contact with the PSA 306, or maylower the PSA assembly 302 a toward the body 304 to make contact.

FIG. 9 is a flowchart illustrating an example method 900 of adhering apressure sensitive adhesive onto a body of a display device. The method900 includes, at 902, placing the PSA assembly comprising a PSA and areleasable support on a PSA application fixture, such as that describedwith regard to FIGS. 3, 4A, and 4B. The releasable support may be on afirst side of the PSA, while an additional liner also may be provided ona second side of the PSA. As such, placing the PSA assembly on the PSAapplication fixture may include, at 904, maintaining the PSA assembly onthe PSA application fixture via an applied vacuum such that the sidehaving the releasable support faces the PSA application fixture. Themethod 900 then includes, at 905, removing the liner from the PSAassembly to expose the PSA. Next, the method 900 includes, at 906,placing a body of the display device on the PSA application fixture, andat 908, while maintaining the PSA assembly on the PSA applicationfixture, aligning a position of the PSA to the body. For example, thePSA may be aligned to the body by positioning a first index feature onthe PSA application fixture to interface with a first reference featureof the body, at 910. As described above with regard to FIG. 5, this mayinclude positioning a first alignment pin on the PSA application fixtureto interface with a first indentation formed in the body, at 912. Insome examples, the first reference feature may comprise an elongatedindentation formed in an inner edge of a deck of the body, as shown inFIG. 5.

The PSA may be further aligned to the body by, at 914, positioning asecond index feature on the PSA application fixture to interface with asecond reference feature of the body. In some examples, this may includepositioning a second alignment pin on the PSA application fixture tointerface with a second indentation formed in the body, at 916. Asexamples, the second reference feature may be a semicircularindentation, an indentation comprising one or more angles, or any othersuitably shaped indentation formed in the inner edge of the deck of thebody that is shaped to accurately interface with a shape of the secondindex feature on the PSA application fixture.

The method 900 further includes, at 918, adhering the PSA to the bodywhile maintaining contact of the first index feature with the firstreference feature and the second index feature with the second referencefeature. The PSA may be adhered to the body by moving the body toward tothe PSA assembly, at 920, or by moving the PSA assembly toward the body.Once the PSA assembly has been adhered in an aligned position, thereleasable support of the PSA assembly may be removed to expose anadhesive side of the PSA, at 922. The method 900 then includes adheringa display module to the body via the PSA, at 924.
